FIELD OF THE DISCLOSURE

This disclosure generally relates to information handling systems, andmore particularly relates to a system and method for providing wirelesspower in a removable wireless charging module.

BACKGROUND

As the value and use of information continues to increase, individualsand businesses seek additional ways to process and store information.One option is an information handling system. An information handlingsystem generally processes, compiles, stores, and/or communicatesinformation or data for business, personal, or other purposes. Becausetechnology and information handling needs and requirements can varybetween different applications, information handling systems can alsovary regarding what information is handled, how the information ishandled, how much information is processed, stored, or communicated, andhow quickly and efficiently the information can be processed, stored, orcommunicated. The variations in information handling systems allow forinformation handling systems to be general or configured for a specificuser or specific use such as financial transaction processing, airlinereservations, enterprise data storage, or global communications. Inaddition, information handling systems can include a variety of hardwareand software components that can be configured to process, store, andcommunicate information and can include one or more computer systems,data storage systems, and networking systems.

A wireless power delivery system typically includes a wireless chargingpad on to which a device can be placed for charging. The device cancommunicate with the pad via near field communication (NFC) to indicatethat the device available to receive power. The wireless power deliverysystem can then wirelessly transmit power to the device.

FIG. 1 illustrates a wireless power delivery system 100 for aninformation handling system. For purposes of this disclosure, theinformation handling system may include any instrumentality or aggregateof instrumentalities operable to compute, classify, process, transmit,receive, retrieve, originate, switch, store, display, manifest, detect,record, reproduce, handle, or utilize any form of information,intelligence, or data for business, scientific, control, entertainment,or other purposes. For example, an information handling system may be apersonal computer, a PDA, a consumer electronic device, a network serveror storage device, a switch router or other network communicationdevice, or any other suitable device and may vary in size, shape,performance, functionality, and price. The information handling systemmay include memory, one or more processing resources such as a centralprocessing unit (CPU) or hardware or software control logic. Additionalcomponents of the information handling system may include one or morestorage devices, one or more communications ports for communicating withexternal devices as well as various input and output (I/O) devices, suchas a keyboard, a mouse, and a video display. The information handlingsystem may also include one or more buses operable to transmitcommunications between the various hardware components.

The wireless power delivery system 100 includes a wireless charging pad102, an information handling system 104, and a wireless charging module106. The wireless charging pad 102 includes a wireless power source 108,an antenna 110, and a landing pad 112. The information handling system104 includes an optical drive bay 114 and pads 116. The wirelesscharging module 106 includes an antenna 118 and a wireless charger 120.The wireless power source 108 is in communication with the antenna 110,which in turn is in communication with the antenna 118 of the wirelesscharging module 106. The antenna 118 is in communication with thewireless charger 120.

The wireless charging module 106 can be shaped to fit within a standardoptical drive bay, such as the optical drive bay 114 of the informationhandling system 104. Thus, the wireless charging module 106 can beinserted into the optical drive bay 114 of the information handlingsystem 104, and can connect with the information handling system via oneor more buses. For example, the wireless charging module 106 can connectwith the information handling system via a communication bus, such as aserial advanced technology attachment (SATA) mini bus 322 (shown in FIG.3), to communicate with the information handling system. The wirelesscharging module 106 can also connect with the information handlingsystem 104 to provide power to the information handling system via ahigh power connector 324 (shown in FIG. 3).

When the wireless charging module 106 is connected to the informationhandling system 104, the wireless charger 120 of the wireless chargingmodule can communicate with the information handling system, via theSATA mini bus 322, to provide information about the wireless chargingmodule. For example, information can include a class of the wirelesscharging module 106, an amount of power that the wireless chargingmodule can provide, a type of the wireless charging module, a maximumamount of voltage that the wireless charging module can provide, and thelike. The information handling system 104 can use the information todetect whether the wireless charging module 106 is compatible with apower system of the information handling system. When the informationhandling system 104 has determined that the wireless charging module 106is a compatible charging module, the information handling system cansent the power system in a ready state to receive power from thewireless charging module.

The wireless charging pad 102 can detect when a device such as theinformation handling system 104 is placed on top the landing pad 112 ofthe wireless charging pad, and can transmit a detect signal in responseto detecting the device. For example, the wireless charging pad 102 candetect the information handling system 104 when a light sensor on thewireless charging pad 102 is covered by the information handling system,by a pressure sensor of the wireless charging pad detecting theinformation handling system, by metal tabs of the wireless charging padbeing placed in physical communication with the information handlingsystem, and the like. The information handling system 104 can receivethe detect signal from the wireless charging pad, and can respond bytransmitting a presence signal to the wireless charging pad. Thepresence signal can include a repeating pulse signal, referred to as achirp, and can also include information associated with the informationhandling system 104 and the wireless charging module 106, such as aclass of the information handling system and the class of the wirelesscharging module. The class of the information handling system 104 andthe class of the wireless charging module 106 can indicate a maximumpower needed for the information handling system, or the like. In anembodiment, the landing pad 112 can be a designated location of thewireless charging pad 102 with a specific orientation for theinformation handling system 104 so that the antennas 110 and 118 canalign properly.

The wireless charging module 106 includes a plastic bottom portion 122of an enclosure of the wireless charging module. The remaining portions,such as front, back, left, right, and top portions, of the enclosure ofthe wireless charging module 105 can be metal, plastic, or any othertype of material capable of supporting and protecting the componentslocated within the wireless charging module. The bottom portion of thewireless charging module 106 is plastic to enable the antenna 118 of thewireless charging module to communicate with the antenna 110 of thewireless charging pad 102. Similarly, the information handling system104 includes a bottom portion 202, which in turn includes a non-metallicportion 204 as shown in FIG. 2.

FIG. 2 shows the information handling system 104 including the bottomportion 202, the non-metallic portion 204, and the pads 116. In anembodiment, an enclosure of the information handling system 104,including the bottom portion 202, is a metal enclosure, such as amagnesium metal alloy. If the metal enclosure of the informationhandling system 104 is between the antenna 118 of the wireless chargingmodule 106 and the antenna 110 of the wireless charging pad 102 of FIG.1, the metal enclosure can prevent a power transfer between the twoantennas.

Thus, the non-metallic portion 204 of the bottom portion 202 can bepositioned so that the non-metallic portion is located below the antenna118 when the wireless charging module 106 in inserted into theinformation handling system 104. The position of the non-metallicportion 204 below the antenna 118 can enable the antenna of the wirelesscharging module 106 to communicate with the antenna 110 of the wirelesscharging pad 102 without having interface from metal enclosure. Indifferent embodiments, the non-metallic portion 118 can be substantiallythe same size as the antenna 118, can be larger than the antenna butsmaller that the wireless charging module 106, can substantially thesame size as the wireless charging module, can be larger than thewireless charging module, or the like. The non-metallic portion 204 canbe composed of any material that does not affect the power transferbetween the antennas 110 and 118.

Referring back to FIG. 1, the wireless charging pad 102 can receive thepresence signal from the information handling system 104, and can thenset an initial power level to be provided from the wireless power source108 to the wireless charging module 106. The initial power level can bea minimum power level available from the wireless charging pad 102, canbe a maximum power level available from the wireless charging pad, orcan be any power level in between the minimum and maximum power levels.The wireless charging pad 102 can then transmit the wireless power tothe wireless charging module 106 via the antenna 110. The wirelesscharging pad 102 can use one or more techniques to provide powerwirelessly, including inductive techniques, resonant inductivetechniques, capacitive transfer techniques, beamed power transfer, suchas laser or microwave transfer, or the like. However for purposes ofdiscussion, it is assumed that the wireless charging pad 102 transferspower wirelessly using inductive power transfer. The plastic bottomportion 122 of the wireless charging module 106, the non-metallicportion 204 of the information handling system 104, and a space 124between the antenna 110 and the antenna 118 can create an air gap forthe inductive power transfer between the two antennas. The amount ofpower needed to be transferred from the antenna 110 to the antenna 118can vary based on the space 124, which can be a calculated distance thatis determined based on the height of the pads 116, the distance from thebottom portion 202 of the information handling system 104 and the bottomportion 122 of the wireless charging module 106, and a distance betweenthe antenna 110 and the top of the wireless charging pad 102. Theantenna 118 of the wireless charging module 106 can receive the wirelesspower from the antenna 110 and can provide the power to the wirelesscharger 120, which in turn can convert the power to be used by theinformation handling system 104.

The information handling system 104 can monitor its current operatingconditions and can determine whether to change a power state of theinformation handling system. For example, if the information handlingsystem 104 is receiving the maximum amount of power from the wirelesscharging pad 102 and then the information handling system enters a lowerpower mode, the information handling system can send a power statechange signal to the wireless charging pad 102. The power state changecan indicate a new power state for the information handling system 104.The wireless charging pad 102 can receive the power state change signaland can adjust the power level provided by the wireless power source 108to the information handling system 104, such that a proper power levelis provided to the information handling system without having excesspower that is not used or not having enough power for the informationhandling system. The information handling system 104 can continuallymonitor its operating mode and can provide any necessary state changesignals to the wireless charging pad 102.

FIG. 3 shows a more detailed embodiment of the wireless power deliverysystem 100 including the wireless charging pad 102, the informationhandling system 104, and a plurality of direct current DC sources 302.The wireless charging pad 102 includes the landing pad 112, which inturn includes a source-to-load limit control module 304, a throttlecontrol module 306, an antenna 308, the wireless power source 108, andthe antenna 110. The antenna 110 is in communication with the wirelesspower source 108. The wireless power source 108 is in communication withthe source-to-load limit control module 304, which in turn is incommunication with the throttle control module 306 and with the antenna308.

The information handling system 104 includes a battery 310, voltageregulators 312, a host/embedded controller (EC) throttle control module314, a near field communication (NFC) alternative Bluetooth Low Energy(BT LE) antenna 316, and a NFC product Electronic Data Identification(EDID) tag 318. The wireless charging module 106 includes a battery 320,the antenna 118, and the wireless charger 120. The antenna 118 is incommunication with the wireless charger 120, which in turn is incommunication with the host/EC throttle control module 314 via thecommunication bus 322. The wireless charger 120 is also in communicationwith the battery 320, with the battery 310, and with the voltageregulators 312 via the power connector 324. In an embodiment, the powerconnector 324 can be a system management bus, and the power connectorcan also include low power pins to provide power to logic components inthe wireless charging module 106.

The voltage regulators 312 can provide multiple regulated voltages todifferent systems loads of the information handling system 104, such asa central processing unit, a memory, a display device, and the like. Thehost/EC throttle control module 314 is in communication with the NFCalternate BT LE antenna 316. The host/EC throttle control module 314 canbe a hardware module, a software module, and/or any combination of ahardware and software module. For example, the host/EC module 314 can bea power management integrated circuit, a power management unit, or thelike. The plurality of DC sources 302 can include an automatic airsource, an alternating current (AC)-to-DC source, and a universal serialbus (USB) power source, or the like.

When the wireless charging module 106 is connected to the informationhandling system 104, the wireless charger 120 can communicate with thehost/EC throttle control module 314 of the information handling systemto provide information about the wireless charging module. For example,information can include a class of the wireless charging module 106, anamount of power that the wireless charging module can provide, a type ofthe wireless charging module, and the like. The host/EC throttle controlmodule 314 can use the information to detect whether the wirelesscharging module 106 is compatible with a power system of the informationhandling system. When the host/EC throttle control module 314 hasdetermined that the wireless charging module 106 is compatible with theinformation handling system, the host/EC throttle control module can setthe power system of the information handling system in a ready state toreceive power from the wireless charging module 106.

When the information handling system 104 containing the wirelesscharging module 106 is placed within a NFC range of landing pad 112 ofthe wireless charging pad 102, the NFC product EDID tag 318 can transmita presence signal, referred to as a chirp, to indicate that theinformation handling system is within range of the wireless chargingpad. The presence signal can be a repeating pulse that can be receivedby the antenna 308, which in turn can provide the presence signal to thesource-to-load limit control 306. In an embodiment, the presence signalfrom the NFC product EDID tag 318 can also include information about thewireless charging module 106, such as a class of the wireless chargingmodule.

When the source-to-load limit control module 304 receives the presencesignal from the antenna 308, the source-to-load limit control moduledetermines whether another signal is received from the throttle controlmodule 306. If a signal is not received from the throttle control module306, the source-to-load limit control module 304 can set an operationlevel of the wireless charging pad 102 to an initial operation level,such as a minimum level. The source-to-load limit control module 304 cansend the operation level to the wireless power source 108, which canreceive power from one of the DC power sources 306.

The wireless power source 108 can then provide power to the antenna 110,which in turn can wirelessly provide the power to the antenna 118 of thewireless charging module 106. The wireless charging pad 102 can use oneor more techniques to provide power wirelessly, including inductivetechniques, resonant inductive techniques, capacitive transfertechniques, beamed power transfer, such as laser or microwave transfer,or the like. In an embodiment, the plastic portion 122 (shown in FIG. 1)of the wireless charging module 106 and the non-metallic portion 204(shown in FIG. 2) of the information handling system 104 can enable thepower to be provided from antenna 110 to antenna 118 via inductive powertransfer.

The antenna 118 can receive the wireless power from the antenna 110, andcan provide power to the wireless charger 120. The wireless charger 120can then convert the power received from the antenna 118 to a powerlevel and a voltage level that can be utilized by the informationhandling system 104, such as forty-five or sixty-five Watts and nineteenand a half volts. The wireless charger 120 can either supply theconverted power to the battery 310 or the voltage regulators 312. Thepower provided to the battery 310 can be used to charge the battery, andthe power provided to the voltage regulators 312 can be supplied at aproper voltage to the remaining components of the information handlingsystem 104. If the battery 310 is fully charged and the informationhandling system 104 does not require the entire amount of power receivedby the wireless charging module 106 from the wireless charging pad 102,the wireless charger 120 can provide the remaining power to the battery320. The power provided to the battery 320 can be used to charge thebattery, which can be used as a secondary battery for the informationhandling system 104.

The host/EC throttle control module 314 can receive information aboutthe power provided by the wireless charging pad 102 from the wirelesscharger 120. The information can include whether the wireless chargingpad 102 is compatible with the wireless charger converter, a totalamount of power that the wireless charging pad is able to provide, orthe like. The host/EC throttle control module 314 can also determineinformation about the information handling system 104, such as apercentage of the batteries 310 and 320 that is charged, an operationmode of the information handling system, and the like.

If the host/EC throttle control module 314 determines that the wirelesscharging pad 102 is not compatible with the class of the wirelesscharging module 106, the host/EC throttle control module can set a flagto cause the wireless charger 120 not to receive power from the wirelesscharging pad. The host/EC throttle control module 314 can also notifythe user, via a display device, that the information handling system 104is not receiving power from the wireless charging pad 102. If thehost/EC throttle control module 314 determines that the wirelesscharging pad 102 is compatible with the wireless charging module 106,the host/EC throttle control module 314 can determine an amount of powerthat is available from the wireless charging pad. If the host/ECthrottle control module 314 determines that the maximum amount of poweravailable from the wireless charging pad 102 is less than the amountneeded to operate the information handling system 104 at maximum power,the host/EC throttle control module can modify an operating mode of theinformation handling system, such as operating below the maximum power.For example, the host/EC throttle control module 314 can cause theinformation handling system 104 to enter a standby or low power mode inresponse to determining that the maximum amount of power available fromthe wireless charging pad 102 is substantially less than the amountneeded by the information handling system. The host/EC throttle controlmodule 314 can cause the information handling system 104 to remain inthe low power mode while the battery 310 is charged to a high enoughcapacity to operate the information handling system. In anotherembodiment, the host/EC throttle control module 314 can reduce theoperational mode the information handling system 104, such that thevoltage supplied to the central processing unit, the memory, and othercomponents of the information handling system is reduced.

If the host/EC throttle control module 314 determines that the wirelesscharging pad 102 can provide more power than needed by the informationhandling system for maximum operation power, the host/EC throttlecontrol module can determine a power state needed for the informationhandling system and can send the power state to the throttle controlmodule 306. When the throttle control module 306 receives the powerstate from the host/EC throttle control module 314, the throttle controlmodule can determine an operation level for the wireless charging pad102. The throttle control module 306 can then send the operation levelto the source-to-load limit control module 304, which in turn candetermine an amount of power to be provided by the wireless power source108. The source-to-load limit control module 304 can send a signal tothe wireless power source 108 to set the power level for the wirelesspower source to provide to the information handling system 104 via theantenna 110.

The wireless charger 120 can receive power from the antenna 118 and canprovide the power to the battery 310, the voltage regulators 312, or thebattery 320. While the wireless charging module 106is receiving powerfrom the wireless charging pad 102, the host/EC throttle control module314 can continually monitor the operational mode of the informationhandling system 104 and can adjust the power state provided to thethrottle control module 306. For example, the information handlingsystem 104 may operate in a maximum power mode, and may switch to a lowpower mode such that the information handling system does not need thesame amount of power. The power state can indicate the amount of powerto be provided to the wireless charging module 106 connected theinformation handling system 104. In this situation, the host/EC throttlecontrol module 314 can determine a new power state and send the newpower state to the throttle control module 306, which in turn can adjustthe operation level of the wireless charging pad 102. The change in theoperation level of the wireless charging pad 102 can result in a changein the amount of power provided to the information handling system 104.

If the wireless charging pad 102 cannot provide the amount of powerrequested by the host/EC throttle control module 314 or any amount ofpower to the information handling system 104, the wireless charging padcan send information to the host/EC throttle control module 314 toindicate the current power available. The host/EC throttle controlmodule 314 can then set a flag to indicate that a certain amount ofpower cannot be received from the wireless charging pad 102. The host/ECthrottle control module 314 can also set a flag when the battery 310 isfully charged, and another flag when the battery 320 is fully charged.The host/EC throttle control module 314 can then send information to thethrottle control module 306 to indicate that the information handlingsystem 104 does not currently need power from the wireless charging pad102.

When the information handling system 104 and the wireless chargingmodule 106 are no longer in communication with the wireless charging pad102, the host/EC throttle control module 314 can clear any flags set.Thus, if the information handling system 104 begins to communicate withthe wireless charging pad 102 again, the communication and setup betweenhost/EC throttle control module 314 and the throttle control module 306can restart as described above. In another embodiment, when theinformation handling system 104 is no longer in communication with thewireless charging pad 102, the host/EC throttle control module 314 cancontinue to maintain the flags indicating that the batteries 310 and 320are fully charged until a point in time, if any, that one or both of thebatteries becomes less than fully charged.

FIG. 4 shows a flow diagram of a method 400 for controlling an amount ofpower provided from a wireless power delivery system. At block 402, apresence signal is received from an information handling system. Thepresence signal can be received at a wireless charging pad via a nearfield communication (NFC) signal. In an embodiment, the presence signalcan be a signal indicating that the information handling system ispresent, can be the signal combined with a class identifier for theinformation handling system, or the like. The class identifier canindicate a maximum amount of power that the information handling systemneeds during operation. At block 404, a determination is made whether awireless charging module is detected, electronic device identification(EDID) information is received, or a second NFC signal is received. TheEDID can include information about the power requirements for theinformation handling system, such as the maximum power the informationhandling system can receive, a nominal power for the informationhandling system, whether the information handling system is charging, ina low power mode, whether the an auxiliary battery needs to be charged,whether the information handling system is in standby mode, or the like.

If a state change, EDID information, and/or a second NFC signal are notreceived, power parameters of the wireless power delivery system arereset and the wireless power delivery system continues to poll theinformation handling system at block 406, and the flow continues asstated above at block 404. The wireless charging pad can provide aminimum power level when the power parameters are reset. If the statechange, EDID information, and/or a second NFC are received, adetermination is made whether an input base source or alternate powersource is available at block 408. If an input base source or analternative power source is not available, then the flow continues asstated above at block 406. If input base source or an alternative powersource is available, then a power state needed for the informationhandling system is set at block 410.

At block 412, the new power state is used to drive a wireless poweroperation level of the wireless charging pad of the wireless powerdelivery system. A local wireless power time event is set at block 414,and then the flow returns to block 412 when the time event expires. Thetimer event can be a length of time to provide power the informationhandling system in the wireless power operation level. At block 416, adetermination is made whether a power level of the wireless powerdelivery system needs to be increased based on the wireless poweroperation level. If the power level needs to be increased, the operationlevel is increased at block 418, and a determination is made whether thepower level is at a maximum at block 420. In an embodiment, adjustingthe operation level directly adjusts the power level provided by thewireless charging pad. If the operation level is not at a maximum theflow continues as state above at block 416. If the operation level is atthe maximum, the control of the wireless power delivery system isupdated based on the power level maximum being reached at block 422, andthe flow continues as stated above at block 410.

However, if the power level does not need to be increased, the operationlevel of the wireless power delivery system is decreased at block 424.At block 426, a determination is made whether a minimum operation levelof the wireless delivery system is reached. If the operation level isnot at a minimum the flow continues as state above at block 416. If theoperation level is at the minimum, the control of the wireless powerdelivery system is updated based on the power level minimum beingreached at block 422, and the flow continues as stated above at block410.

FIG. 5 shows a flow diagram of a method 500 for controlling an amount ofpower to be received at an information handling system from a wirelesspower delivery system. At block 502, a determination is made whether awireless charging module is detected in the information handling system.When the wireless charging module is detected, a determination is madewhether the wireless charging module is valid at block 504. Thedetermination of whether wireless charging module is valid can bewhether the wireless charging module is compatible with the power levelrequirements of the information handling system. If the wirelesscharging module is not valid, the flow continues as stated above atblock 502. When the wireless charging module is valid a determination ismade whether a valid wireless power source, such as a wireless chargingpad, is available at block 506. If a valid wireless power source is notavailable, then the flow continues as stated above at block 502. If avalid wireless power source is available, a determination is madewhether the information handling system is in bypass mode at block 506.If the information handling system is in bypass mode, then a minimumpower level for the information handling system is set based on theinformation handling system being in a bypass mode at block 508. Atblock 510, a determination is made whether a stable host power isdetected for the information handling system. If a stable power is notdetected, the flow continues as stated above at block 508. If a stablepower is detected, the flow continues as stated above at block 506.

If the information handling system is not in the bypass mode, a powerstate of a needed power level is set at block 512. At block 514, analternate near field communication (NFC) antenna is engaged and a powerstate is transmitted to the wireless charging pad. A local wirelesspower time event is set at block 516, and then the flow returns to block514 when the time event expires. The timer event can be a length of timeto provide power the information handling system in the wireless poweroperation level. At block 518, an operating mode of the informationhandling system is changed. A determination is made whether a powerstate change is needed at block 520. When a power state change isneeded, a new power state is determined at block 522, and the flowcontinues as stated above at block 512.

As shown in FIG. 6, an information handling system 600, such asinformation handling system 100, can include a first physical processor602 coupled to a first host bus 604 and can further include additionalprocessors generally designated as n^(th) physical processor 606 coupledto a second host bus 608. The first physical processor 602 can becoupled to a chipset 610 via the first host bus 604. Further, the n^(th)physical processor 606 can be coupled to the chipset 610 via the secondhost bus 608. The chipset 610 can support multiple processors and canallow for simultaneous processing of multiple processors and support theexchange of information within information handling system 600 duringmultiple processing operations.

According to one aspect, the chipset 610 can be referred to as a memoryhub or a memory controller. For example, the chipset 610 can include anAccelerated Hub Architecture (AHA) that uses a dedicated bus to transferdata between first physical processor 602 and the n^(th) physicalprocessor 606.
